Invitae RCV000640553 SCV000762146 uncertain significance Capillary malformation-arteriovenous malformation syndrome 2024-01-17 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 925 of the RASA1 protein (p.Ile925Val). This variant is present in population databases (rs140786299, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with RASA1-related conditions. ClinVar contains an entry for this variant (Variation ID: 533443). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics RCV002440280 SCV002746241 uncertain significance Cardiovascular phenotype 2021-07-01 criteria provided, single submitter clinical testing The p.I925V variant (also known as c.2773A>G), located in coding exon 22 of the RASA1 gene, results from an A to G substitution at nucleotide position 2773. The isoleucine at codon 925 is replaced by valine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
PreventionGenetics, part of Exact Sciences RCV003965351 SCV004780857 likely benign RASA1-related condition 2023-09-27 criteria provided, single submitter clinical testing This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications).
